To ALL wHoM 1T MAY coNoERN:

'Be it known that I, HARVEY SILVER, of Lowell, in the countyof'Middlesex, and the State of Massachusetts, have invented certain newand useful Improvements in Spinning-Machine Flier's, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, making part of this specification, inIwhich- Figures 1 represents an ordinary sp inning-machine flier, with myimprovements applied thereto.

Figure 2, atransverse section, on the line A B, of tig. l.

Figure 3, an edge view, after a portion of the arm C has vbeen removed.

Figure 4a central longitudinal section of the middle portion of the armD and of my improvement, considerably enlarged.

-This invention consists in a new and very useful method of connecting,attaching, or applying the guide- Wires .or guide-'pins to the arms orsides of the iers of spinning-machines, or the iliers of all kinds ofmachines which are used for spinning or twisting yarn or thread, or fordrawing roving of cotton-wool or worsted or other fibrous substances,and has for its object to greatly facilitate the removal of the old andworn guide-pins and the application of new ones, also to prevent thearms or sides being w'orn or cut by the yarn or thread which passesthrough the nose of the dier and one or more times round either of thearms and under -o ne of the guidepns to the bobbin, which is placed onthe spindle between the two arms.

In the ordinary mode oi' attaching and securing the guide-wires orguide-pins to the arms or sides of spinning-fliers, a small hole isdrilled through eachof the arms, and into and through this hole isinserted, driven, and rixveted a small wire, which isbent downwards,forming a. sort of hook. The thread or yarn which passes one or moretimes round the arm of the flier, and under the hook or guide-wire tothe bobbin, so cuts the guide-wire, that it has to lie-removed in ashort time and a new guide-wire substituted; besides, the arm is sobadly cutby the yarn or thread, that new iliers ha'vc to be put in theplace of worn iers much oftener than is desired. In removing theguide-wires or guidefpins, which are secured to the dier-arms in theordinary way, it is necessary to cut or tile oli` the riveted ends, and-then punch out the guide-pins one at a time, holding` each iiier in avise or a grooved iron'bloek, thus making the process a very slow andexpensive one. a

To prevent the cutting or wearing of the lier-arms by the yarn orthread, and to greatly facilitate the removal and replacing oftheguide-pins, I secure to opposite sides of the Hier-arms a saddle, e, ofhardened st-eel, olaother hard metallic substance, at the top end ofwhich is a projecting portion, which is turned or bent over anddownwards, as shown in the drawings, forming a sp1-ing. Through themiddle portion of this spring, between the bur, 7c, and the end, b,thereof, a holeis formed, and opposite this holo, and through thesaddle, is another hole like the first. -The guide-pin e is inserted inthe hole in the saddle, iirst drawing the spring outward,

then allowing the spring` to close into the opposite end of theguide-pin, one end of which bears against the ilier-arm, as at d, fig.4, and the other end against a disk or plate secured to the outside ofthe spring portion, or formed in one therewith. The saddle, e, isgenerally soldered to the arm of the lier, to obviate the necessity ofdrilling the flier-arm, which drilling weakens it considerably. Theprincipal wear or cutting of the ordinary ilierarm is at the junction ofthe guide-pin with the nrnJ,-or just below thepin. It will he readilyseen that by the use of the hardened saddle the yarn or thread cannotcut or wear the arm of the flier, and by means of the spring portion,and the holes in the latter and in the saddle, the guide-pins may beeasily removed and replaced, without even removing the iiior from thespinning-machine, or disturbing the iiier in any way.

It will also be observed that'in they. present ease the guide-pins areof glass. This glass pin, or a pin made of porcelain or a similarsubstance, may in some c'ases wear longer than hardened steel, but formost kinds of spinning I prefer the steel pin, which is much easier andcheaper made, and less liable to get broken or injured, and is largerand more durable than in any other flier.

. The hardened saddle e may be applied to the Hier-arm, and the ordinaryhooked guide-wire inserted, in the usual way. In this case the saddleprotects the nrm and saves the dier, whether or not the Spring portionis combined with the saddle, as described.

Having fully described my invention, what I claim as new, and desireto'secre by Letters Patent, is

1. The spring portion, shown and'described, when combined with thesaddle and constructed and arranged for the removal and replacing of theguide-pin e, for the purpose and substantially as described.

2. The guide-pin e, when construeted as described, 4and applied to thespringportion and the saddle, c, as and for the purpose described. l f

3. The combination of the saddle, springport'ion, :ind pin with theflier-arm or arms, for the purpose and substantially as described.
